@article{Gorchinskiy2015AHC, title={A higher-dimensional Contou-Carr{\`e}re symbol: local theory}, author={S. Gorchinskiy and Denis Vasilievich Osipov}, journal={Sbornik: Mathematics}, year={2015}, volume={206}, pages={1191 - 1259} }
We construct a higher-dimensional Contou-Carrère symbol and we study some of its fundamental properties. The higher-dimensional Contou-Carrère symbol is defined by means of the boundary map for -groups. We prove its universal property. We provide an explicit formula for the higher-dimensional Contou-Carrère symbol over and we prove the integrality of this formula. We also study its relation with the higher-dimensional Witt pairing.
